Yeah, I can remember the 90s and 2000s (not to mention millennia before that) where the shape of the Earth wasn't in dispute. Even 2000 years ago educated people knew the Earth was round.
Social media ruined humanity
Government said Furbies was a spy device....lol.
Government created Y2K hysteria to boost economy with "Y2K compliant" devices. Government facilitated that conspiracy with the two digit year format.
Government was concerned Saddam was allowed to buy PS2s because he was building a super computer...lol
That was early 2000s. Government wasn't trustworthy but educated people went along with all of the above...
